EFFECTS OF HIGH-PREFERENCE SINGLE-DIGIT MATHEMATICS PROBLEM COMPLETION ON MULTIPLE-DIGIT MATHEMATICS PROBLEM PERFORMANCE

The purpose of this study was to examine the effects of a sequence of three single-digit (1 digit × 1 digit) multiplication problems on the latency to initiate multiple-digit (3 digit × 3 digit) multiplication problems for 2 students in an alternative education school. Data showed that (a) during the preference assessment, both students selected the single-digit problems in a majority of the sessions, and (b) intervention resulted in a decrease in latency between problems for both students. Results are discussed in relation to using high-preference sequences to promote behavioral momentum in academic content areas.     

HPA-Axis Activation as a Key Moderator of Childhood Trauma Exposure and Adolescent Mental Health

Individual differences in a child’s sensitivity to stress may influence whether youth exposed to trauma develop symptoms of psychopathology. We examined the interaction between HPA-axis reactivity to an acute stressor and exposure to different types of childhood trauma as predictors of mental health symptoms in a sample of youth. Youth (n?=?121, ages 9–16; 47% female) completed a standardized stress task, including 5 post-stress salivary cortisol samples. Parents also completed the Child Behavior Checklist as a measure of child internalizing and externalizing symptoms in the past month, and completed the Early Trauma Inventory (ETI) as a measure of their child’s trauma exposure. More emotional abuse and non-intentional trauma were associated with greater internalizing symptoms. Youth exposed to physical abuse who demonstrated slower HPA-axis reactivity had elevated internalizing and externalizing symptoms. Youth exposed to emotional abuse or non-intentional traumatic events who demonstrated faster HPA-axis reactivity had elevated internalizing and externalizing symptoms. Profiles of exaggerated or attenuated HPA-axis reactivity to acute stress may be risk factors for psychopathology in children facing different stressful social environments.     

Acute Aerobic Exercise Enhances Students’ Creativity

The purpose of this study was to evaluate the effectiveness of an aerobics games class on creativity in children during the school day. Participants were 96 students (age = 9.84 ± 1.12 years), 48 girls and 48 boys. The students were randomly assigned to the experimental group (EG, n = 48) or the control group (CG, n = 48). The Prueba de Imaginación Creativa-Niños (PIC-N) test was employed to assess narrative and graphic creativity. The EG took part in an aerobic games session lasting 45 min; the CG did not take part in a physical education class on that school day. As for group × time interaction, the EG experienced significant improvements in all creativity variables except in graphic originality, graphic titles, and graphic details. The CG did not improve any creativity variables. The findings suggest that acute aerobic exercise can enhance students’ creativity, which could be important for academic achievement.     

Emotional Intelligence Profiles in College Students and Their Fathers’ and Mothers’ Parenting Practices

The present study has two objectives: first, to analyze whether the dimensions that make up emotional intelligence (attention, clarity, and repair) give rise to different profiles of university students, and secondly, to determine whether these different profiles are differentially associated with the parenting practices that students report with regard to their fathers and mothers. Results obtained indicate the existence of different profiles of college students. The profile that corresponds to adequate emotional skills presents a lower score in attention, but higher scores in clarity, and especially in mood repair. The other two profiles are inadequate, in the first case because a higher score in emotional attention is accompanied by low scores in mood repair, and in the second case because low scores are presented in all three dimensions. Likewise, we verified the existence of significant differences in the educational practices of parents, the adequate profile is characterized by greater use of parenting dimensions considered to be positive, and at the same time, lower scores on dimensions considered to be negative. One of the dysfunctional profiles is associated with higher scores in positive practices, and is also associated with higher scores in practices considered to produce a negative effect. The second dysfunctional profile is associated with higher scores on the dimensions considered to be negative and lower scores on positive dimensions.     

The Trait Anxiety Scale for Children: A validation study for European Portuguese children and adolescents

The State-Trait Anxiety Inventory for Children is a self-report instrument inspired on the State-Trait theory extended by Spielberger that measures a momentary state of anxiety (state) and a stable tendency to experience anxiety (trait). This study presents an exploratory adaptation of the Trait Scale and provides its psychometric properties for European Portuguese children and adolescents. The influence of sex and age were also explored. Our sample, composed of 402 participants aged 8–14 years, revealed a mean anxiety value of 28.37 (SD = 5.99). As expected, females revealed higher levels of anxiety than boys. Higher anxiety was obtained in our youngest group as compared to the oldest group. The exploratory factor analysis led to retaining only 16-items that presented acceptable adjustment to a one-factorial solution. Good indexes were obtained in the confirmatory analysis. The results also revealed good internal consistency and good test-retest reliability. Our results provide initial evidence that this scale is adequate to measure trait-anxiety in European Portuguese young people.     

Intimate Partner Violence Within Gay Male Couples: Dimensionalizing Partner Violence Among Cuban Gay Men

Using a quantitative–qualitative mixed design, the current study investigated relationship violence within 35 gay male couples living in Santiago, Cuba. Informants narrated how violence was enacted within their relationship. Qualitative analyses revealed men’s construction of masculinity and the sequelae of economic hardships—which led to economic emasculinization—were primary contributors to relationship abuse. Gendered interpretations to the display of heightened masculinity contributed to intimate partner violence. Enacted interpersonal violence was not meaningfully associated with alcohol consumption or to personality measures. We suggest the economic constraints that are perceived by couples to precipitate relational stress may be similar across heterosexual and gay/lesbian couples, and that the relational power accorded to economic privilege cannot be aligned fully by gender.     

Hippocampal PKA/CREB pathway is involved in the improvement of memory induced by spermidine in rats

Spermidine (SPD) is an endogenous polyamine that modulates N-methyl-D-aspartate (NMDA) receptor function, and has been reported to facilitate memory formation. In the current study we determined whether or not the PKA/CREB signaling pathway is involved in SPD-induced facilitation of memory of inhibitory avoidance task in adult rats. The post-training administration of the cAMP-dependent protein kinase (PKA) inhibitor, N-[2-bromocinnamylamino)ethyl]-5-isoquinoline sulfonamide [H-89, 0.5 ρmol intrahippocampal (ih)] or the antagonist of the NMDA receptor polyamine-binding site (arcaine, 0.02 nmol ih) with SPD (0.2 nmol ih) prevented memory improvement induced by SPD. Intrahippocampal administration of SPD (0.2 nmol) facilitated PKA and cAMP response element-binding protein (CREB) phosphorylation in the hippocampus 180 min, but not 30 min, after administration, and increased translocation of the catalytic subunit of PKA into the nucleus. Arcaine (0.02 nmol) and H-89 (0.5 ρmol) prevented the stimulatory effect of SPD on PKA and CREB phosphorylation. These results suggest that memory enhancement induced by the ih administration of SPD involves the PKA/CREB pathways in rats.     

Familial multiple sclerosis with repetitive relapses of manic psychosis in two patients (mother and daughter)

The clinical presentation of multiple sclerosis (MS) with psychiatric symptoms is uncommon but it is believed that MS patients are twice as likely to be afflicted with bipolar disorder as the general population. We report two cases (mother and daughter) of MS presenting with bipolar disorder in the form of recurrent manic psychosis and whose outcome was favourable with neuroleptics and corticosteroids. In both cases we found multiple hypersignal lesions on brain magnetic resonance imaging (MRI), especially in the right frontal lobe where we observed signs of activity. Apart from clinical and radiological concordance, the patients exhibited similar class I HLA alleles and identical class II HLA alleles. We focused discussion on whether there may be a common genetic susceptibility to both illnesses or whether MS caused psychiatric manifestations. The coincidence of psychiatric and neurological symptoms in most relapses supports the second hypothesis.     

Working memory and executive control: inhibitory processes in updating and random generation tasks

Working Memory (WM) span predicts subjects' performance in control executive tasks and, in addition, it has been related to the capacity to inhibit irrelevant information. In this paper we investigate the role of WM span in two executive tasks focusing our attention on inhibitory components of both tasks. High and low span participants recalled targets words rejecting irrelevant items at the same time (Experiment 1) and they generated random numbers (Experiment 2). Results showed a clear relation between WM span and performance in both tasks. In addition, analyses of intrusion errors (Experiment 1) and stereotyped responses (Experiment 2) indicated that high span individuals were able to efficiently use the inhibitory component implied in both tasks. The pattern of data provides support to the relation between WM span and control executive tasks through an inhibitory mechanism.
